Expect a brief decision statement, an evidence register, credible alternatives, a pre-mortem, explicit conflicts and a record of why the founder chose a path. The adviser should not claim ownership of the decision or promise that their recommendation will maximise growth.
The minimum should fit on a handful of pages: decision/date/owner; ranked assumptions; supporting and disconfirming facts; option matrix; cash downside; stakeholder implications; a reversible first action; and a checkpoint. A recommendation without a condition that would change it is not sufficiently testable.
